Cool!
Sometimes as I clean seeds, I'll separate the slightly smaller ones from the slightly larger ones. But I've never tested to see if they grow out slightly different plants.
Usually I pick out and throw away anything that looks different from the majority ... I'm not sure why, really.
When cleaning Alyssum seeds (Lobularia maritima ), I could barely distinguish the mature seeds from what I thought were immature seeds and chaff.
I found out why when I germination-tested the "chaff". It germinated at least as well as the "mature seeds". Oh, well. I had saved both, so it was OK.
